A live-singing Beyoncé took the Super Bowl stage last night for a halftime performance that both reunited Destiny's Child and was so electric, it may have contributed to the stadium's ensuing blackout.

Rubin Singer dressed the pop star for the occasion, and had been working on the her look—an armor-inspired leather bodysuit with black lace panels, a cropped leather motorcycle jacket, and a micro-mini skirt—since Thanksgiving, with no less than five fittings and 200 hours spent creating the pieces. "My seamstresses were assembling all of the leather and exotic skins individually by hand," Singer said. "All of the pieces were constructed on her body, [and] we had to make the body suit have a tremendous range of motion and flexibility."

The stage costumes are based on Singer's upcoming Fall 2013 collection, influenced by Norse mythology, Helmut Newton imagery, and Marlene Dietrich's play on masculine and feminine. The designer also created Michelle Williams's halftime look and the jackets for the show's 120 backup dancers.
